Never thought of mixing cocktail during football games …. but hell why not. It will you get blastered much faster than any light beer. Promise!
All you do is fill the watertight inner chamber with your favourite mixers and chuck in some crushed ice. Then screw the two halves together via a nifty interlocking mechanism and get throwing. You can even yell ‘hut hut hut!’ and similarly comical gobbledegook as you hurl your booze-fuelled prolate spheroid towards your wide receiver. Well, towards your bewildered mates.
